CALL-WHISTLE.

SPECIFICATION forming part of Letters Patent No. 250,083, dated November 29, 1881.

Application filed October 24, 1881.

To all whom it may concern Be it known that I, CHARLES S. LEET, a citizen of theUnited States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented new and useful Improvements in Call-Whistles, of which the following is a specification.

This invention relates to the details of the construction of an improved call-whistle for huntsmen and others, the object being to embody all the requisite elements of a whistle'in the form of a complete metallic cartridge, and to so improve the construction thereof as to insure more effective operation of the twitterball usually inclosed in such whistles.

In the drawings forming part of this specification, Figure 1 is a side elevation of a callwhistle construct-ed according to my invention. Fig.2 is avertical section. Fig.3 is a section of the mouth-piece. Fig. 4 is an end view of the mouth-piece, looking toward the interior.

Fig. 5 is-an edge view of the air-diaphragm. Fig. 6 is a plan view of the same. Fig. 7 is an edge view of the frictional base-piece. Fig. Sis a plan view of the same. Fig. 9 is a section of the whistle-body, and Fig. 10 illustrates the twitter-ball.

In the drawings, 0 is the whistle-ease. a is the mouth-piece. c is the air-diaphragm. '0 isthe frictional base-piece, and w is the twitterall.

The case or body of the whistle c is made of suitable metal or other material, in the wellknown form of a metallic cartridge-shell, in one side of which is formed the usual embouchure for the outward escape of air, and to the head thereof is secured a suspending-ring.

The mouth-piece a of the whistle is a short conical tube made in the form of a cartridgeball, its point being perforated for the admission of air, and having around its body the usual lubricant-grooves.

The air-diaphragm e is of the usual formused in whistles.

A disk, v, is made of rubber, leather, or textile material, having a slightly-frictional surface; or it may be made of metal having its surface suitably roughened, and said disk is of such diameter as to make it retain its place (No model.)

in the case 0 when crowded into it near the head of the case, as in Fig. 2.

The twitter-ball x is, as usual, made of any light suitable material, such as wood, cork, 850.

The case 0 having been made as described and shown, the frictional disk n is inserted therein, the ball :0 is next placed in the case above said disk,and the diaphragm is secured therein just above the said embouchure on its side. -The said diaphragm c is made slightly tapering, the diameter of its face, toward the head of case 0, being greater than its upper or outer face, so that the lower edge of the mouthpiece a may enter between the upper part of its periphery and the case, in which manner the mouth-piece a is next applied to the case 0, and the edge of the latter around said diaphragm is crimpcd upon the lower end of the mouth piece and diaphragm, thus securing said parts firmly together and completing the whistle.

The frictional disk 4), which is placed in the base of the case 0, is an important feature in whistles of this class, as it serves to insure a constant bounding movement of the ball 00, by which the essential twittering sound of the whistle is produced, and without which said disk the ball will rest immovable. Rubber is the most preferable material from which to make said disks; but other suitable material may be employed.

What I claim as my invention is 1. As a new article of n'lanut'acture, a callwhistle consisting of abody or case, c, made in the form of a cartridge-shell, and of a hollow mouth-piece, a, made in the form of a cartridgeball, said case and mouth-piece being combined to form a whistle having the form of a metallic cartridge, and provided with the diaphragm c and a suitable opening for the escape of air, substantially as set forth.

2. In a call-whistle, the disk '0, constituting a frictional surface at the base of the case 0, substantially as and for the purpose set forth.
